Abstract: A B S T R A C T        METHOD TO PASSIVATE METALS DEPOSITED ON A  CRACKING CATALYST DURING REDUCED CRUDE PROCESSING     Contaminating metals including nickel, vanadium, iron and copper are deposited on a fluid cracking catalyst during the processing of carbo-metallic oils such as reduced crude or topped crude. These contaminating metals lead to undesirous side reactions such as dehydrogenation, coking and methyl clipping which adversely affect conversion and gasoline selectivity. An improved method and process is described for passivating these metals by treatment with a reducing gas such as ammonia.  The ammonia is added as gaseous ammonia or in the presence of diluents such as nitrogen, carbon dioxide, flue gas, fuel gas and steam. The reaction of ammonia with vanadium produces vanadium nitride which is water insoluble and facilitates the disposal of high vanadium containing spent catalyst by landfill techniques.

Abstract: ABSTRACT OF THE DISCLOSURE          The disclosed current transformer comprises a tubular electrically conducting member of a circular cross section connected to one end of a primary winding in the form of a tubular electrically conducting coil having a single turn, a cruciform conducting member coaxially disposed within the tubular member to be connected to the other end of the coil, and a hollow cylindrical dielectric member coaxially disposed within the tubular member to form an incoming and an outgoing flow path between the tubular and dielectric members and between the dielectric and cruciform members respectively.  The tubular coil and the tubular member are wrapped in an insulating member and a secondary winding is wound around the primary winding through the insulating member.  The transformer is immersed in a dielectric fluid a part of which fills the two flow paths and the interior of the primary winding communicating with them.

Abstract: ABSTRACT OF THE DISCLOSURE    A conventional gas oven having exhaust holes in the high air pressure region of a heating chamber has a drawback that when a circulation fan is rotating, hot air is con-stantly discharged to cause a great heat loss.  According to the present invention, exhaust holes are provided in or adjacent a region where the pressure becomes negative owing to the suction of a circulation fan when the gas combustion is off, with the result that there is no possibility of hot air being unnecessarily discharged in the gas combustion-off period and that in the gas combustion-on period the amount of discharge is automatically controlled according to the combustion rate.  Thus, the invention is characterized by quick temperature rise and the saving of energy, consuming less fuel.

Abstract: ABSTRACT         A process for the in situ reduction of the hydrogen sulfide concentration of n gas derived from A subsurface formation of hydrocarbon material.  The process comprises providing an aqueous electrolyte in contact with the formation and providing at least two electrically conductive elements, constituting an anode and a cathode, in contact with such electrolyte.  A controlled amount of electrical current is passed from a direct current source through the formation between the electrically conductive elements at a voltage of at least 0.3 volts and the current is controlled relative to the composition of the material and the ambient conditions adjacent to the elements are controlled to heat the surface of each element during application of the voltage thereacross to a temperature which is less that 500°F, thereby to yield a gas which has a hydrogen sulfide content substantially less than the gas naturally occurring in the formation.  A notable advantage of the present invention over prior art process involving electrical treatment of subsurface formations is that it produces high Btu fuel gas having significantly reduced hydrogen sulfide levels under relatively moderate operating conditions.  Moreover, the process of the present invention produces satisfactory results in areas where existing recovery technology has been ineffective.

Abstract: PHA.21116                 26                    22-04-83 ABSTRACT: "High frequency oscillator-inverter ballast circuit for discharge lamps", A current fed high frequency oscillator-inverter ballast circuit includes a parallel resonant tank circuit for driving a pair of series connected discharge lamps via a series ballast capacitor. A regenerative power supply switches on when a fluctuating main DC supply voltage drops below a given level thereby providing a constant level auxiliary DC supply voltage to the oscillator inver-ter to maintain oscillation and lamp operation. When the main DC supply voltage exceeds said given level, the re-generative power supply switches out. The oscillation fre-quency is f2 during operation of the main supply and auto-matically switches to a frequency f1 when the regenerative power supply takes over. The frequency shift is automatic during each hal cycle of 50 to 60 Hz AC supply and is in a direction so as to maintain lamp current relatively con-stant. A novel high frequency leakage transformer is pro-vided to couple the high frequency inverter to the dis-charge lamp load to provide both a current limiting (bal-last) action and automatic control of the lamp heater cur-rent to maintain high  efficiency operation.

Abstract: Abstract of the Disclosure An oxygen-fuel burner of the rocket burner type includes a graphite burner block (11) for direct exposure to the interior of a furnace, and a cylindrical combustion chamber (115) formed through the hot face of the burner block and extending into the burner block. An oxygen supply conduit (15) delivers oxygen to the combustion chamber along the center line of the combustion chamber and fuel supply ducts (109 and 110) deliver fuel to the combustion chamber at the concave surface of the combustion chamber, whereby fuel surrounds the stream of oxygen. Excess oxygen can be suplied by the nozzle (82) to provide more oxygen than consumed by the flame, whereby the excess oxygen is preheated as it passes through the flame and can be used in the lancing process in the refining of steel.

Abstract: ABSTRACT         In a device for catching leaked liquid for use in a ship carrying a low temperature liquid in a storage tank which is supported on the bottom of a ship's hold by means of tank supporting structures which prevent horizontal displacement, a leaked liquid receiving pan is disposed below an engaging member which extends downwardly from the bottom of the tank.  The low temperature liquid leaked from the tank and falling between the engaging member and a heat insulating layer surrounding the tank is received by the leaked liquid receiving pan and does not reach the bottom of the ship's hold.  Thus the bottom of the hold is prevented from being cooled.  Prior to this invention, the problem of super cooled liquids leaking on a ship's hold and causing structural weakness was overcome by either constructing ships of special steel or providing an extra insulating jacket around the tank.  Both these measures were uneconomical.  Because such structural steel members are cooled  by the leaked liquid locally and at extremely low temperature, the strength of the ship is adversely affected.  The present invention provides a simple economical solution.

Abstract: ABSTRACT     A valve includes a molded plastic body portion having an inter-nal chamber forming a valve seat having inlet and outlet openings.   A plastic plug member is rotatably positioned in the valve seat and has a flow passage which in the open position of the valve communicates with the inlet and outlet openings.   Pipe fittings of the valve body communicate with the valve seat and are aligned with the inlet and outlet openings. Each fitting is coupled to a conduit of a piping system by a nut threaded into the respective fitting to urge a wedge-shaped collar into frictional engagement with the conduit.  The nut surrounds the collar which is advanced by the nut into the fitting until a radial shoulder on the nut abuts the end of the fitting so that the end of the nut in the fitting applies a controlled compressive force upon a gasket seal to effect a fluid tight connection of the conduit to the fitting.
